Eastside
Consultants performed surveying & engineering
services to develop this 40-acre parcel into a
70-lot subdivision with separate tracts for Sensitive
Areas, Utilities, and Drainage. Itís only one
one of numerous single-family plats designed and
surveyed by our firm.

Beginning
with an overall boundary survey and topographic
mapping, a project such as this requires consideration
of both economic and environmental constraints.

Drainage
Design

Most
projects which create impervious surfaces (hard
surface which either prevents or retards the entry
of water into the soil as it would under natural
conditions) such as a roads and buildings, must
meet jurisdictional requirements for appropriate
drainage. Drainage in this context refers to the
collection, conveyance, containment and/or discharge
of surface and storm water runoff.

Typical
drainage facilities that may be required for new
construction include detention/retention storage,
as shown in these ponds, and/or water quality
treatment facilities. Detention facilities release
surface and storm water runoff from the site at
a slower rate than it is collected by the drainage
facility system. Retention facilities simply collect
and hold surface and storm water runoff with no
surface outflow. Water quality treatment facilities
reduce pollutants once they are already contained
in surface and storm water runoff. Water quality
facilities when used singly or in combination,
reduce the potential for contamination of surface
and/or ground waters.

Examples
of retention/detention as well as water quality
facilities include, but are not limited to, open-air
ponds, underground vaults, and bio-swales.

Road
& Street Design

Local
governments, for the purposes of consistency and
safety, have standardized their own requirements
for most streets and roads within their jurisdiction.
In addition to safety, other considerations include
convenience, a pleasant appearance, proper drainage
and economical maintenance. Governmental standards
also provide requirements for the location and installation
of utilities within rights-of-way. Engineering criterion
to consider when designing an access road include,
but are not limited to, road type, standard design
and right-of way widths, stopping and entering sight
distance, whether curbing, shoulder or ditching
are allowed or required, minimum and maximum grades,
turning radii within a cul-de-sac, and emergency
vehicle access.

Once
the access road has been designed, our field crews
provide the actual locations for construction,
the beginning of which is shown here for a local
street ending in a cul-de-sac.

Land
Surveying

Land
surveying is a large portion of the work done by
Eastside Consultants. This work ranges from residential
lot surveys for fence construction, to large mapping
projects for planning and major subdivisions. Eastside
Consultants is also regularly contracted to establish
boundary lines for the U.S. Forest Service, and
other large landowners in heavily timbered, mountainous
terrain. During the course of these surveys the
original section corners, set in the 1800's, must
be identified and perpetuated for future surveys.

As
a precaution against corners being destroyed in
heavily forested areas, we will frequently "scribe"
a bearing tree, as shown here, as a reference
to the corner. This will enable others to re-establish
the corner based on our Record of Survey.

Route
Surveying

Eastside
Consultants specializes in linear route surveys
for projects such as pipelines and roads.
This work typically involves setting up a control
network over a corridor which runs for several miles.
Determining the best route alternative is usually
complicated by various topographic and
environmental constraints, which our field crews
are well equipped to handle.
